Computer Organization Basics

What is the main function of the CPU in a computer system?

• To walk the dog

• To execute instructions and perform calculations

• To brew coffee

• To bake cookies

Explain the concept of Memory Hierarchy and its importance in computer organization.

• Memory Hierarchy only increases memory access time

• Memory Hierarchy is crucial in computer organization as it enhances system performance by providing faster access to data, reducing memory access time, and optimizing memory utilization.

• Memory Hierarchy slows down system performance

• Memory Hierarchy is irrelevant in computer organization

How does Input/Output Organization play a crucial role in the overall performance of a computer system?

• Input/Output Organization impacts data transfer speed and efficiency, reducing bottlenecks and enhancing system performance.

• Input/Output Organization is only relevant for aesthetic purposes

• Input/Output Organization only affects the physical appearance of the computer

• Input/Output Organization has no impact on system performance

Define Cache Memory and discuss its significance in improving system performance.

• Cache memory is essential in reducing the average time to access data from the main memory, thereby enhancing system performance.

• Cache memory is not necessary as modern systems can operate efficiently without it.

• Cache memory is only used for storing temporary files, not for improving system performance.

• Cache memory slows down the system by increasing the time to access data from the main memory.

What are the stages involved in Pipeline Processing and how does it enhance processing speed?

• The stages involved in Pipeline Processing are Instruction Fetch, Instruction Decode, Execution, Memory Access, and Write Back. It enhances processing speed by allowing multiple instructions to be processed simultaneously.

• Pipeline Processing involves only one stage called Execution. It enhances processing speed by simplifying the process.

• The stages involved in Pipeline Processing are Input, Process, Output, and Feedback. It enhances processing speed by reducing the number of stages.

• The stages involved in Pipeline Processing are Pre-fetch, Decode, Execute, and Store. It enhances processing speed by increasing the complexity of each stage.

Describe the Von Neumann architecture and its impact on modern computer systems.

• The Von Neumann architecture is a computer design model that stores program instructions and data in the same memory unit, consisting of a CPU, memory, input/output devices, and a control unit. It has had a significant impact on modern computer systems by enabling the development of versatile and efficient general-purpose computers.

• The Von Neumann architecture has had a minimal impact on modern computer systems due to its limitations.

• The Von Neumann architecture consists of only a CPU and memory unit, excluding input/output devices and a control unit.

• The Von Neumann architecture is a computer design model that uses separate memory units for program instructions and data.

What is the role of ALU (Arithmetic Logic Unit) in the CPU?

• Controls network connectivity

• Performs arithmetic and logical operations

• Regulates power consumption

• Manages the operating system

Discuss the difference between RAM (Random Access Memory) and ROM (Read-Only Memory).

• RAM is used for long-term data storage, while ROM is used for temporary data storage.

• RAM is non-volatile and stores permanent data, while ROM is volatile and used for temporary data storage.

• RAM is volatile and used for temporary data storage, while ROM is non-volatile and stores permanent data.

• RAM is non-volatile and used for temporary data storage, while ROM is volatile and stores permanent data.

Explain the concept of Virtual Memory and its implementation in computer systems.

• Virtual Memory is used to store temporary internet files on a computer.

• Virtual Memory is implemented in computer systems by using a combination of hardware and software. The hardware component includes the Memory Management Unit (MMU) that translates virtual addresses to physical addresses. The software component involves the operating system managing the mapping of virtual memory addresses to physical memory locations, handling page faults, and swapping data between RAM and disk when necessary.

• Virtual Memory is a software-only concept with no hardware involvement.

• Virtual Memory is a physical memory module installed in computers.

How does the concept of Registers contribute to the efficiency of CPU operations?

• Registers have no impact on the efficiency of CPU operations

• Registers cause data corruption and errors in CPU operations

• Registers provide fast access to data, reducing the need to fetch data from slower memory locations, thus speeding up CPU operations.

• Registers slow down CPU operations by introducing additional complexity
